Been a paying customer for some years now and a free user for much longer, and am having the same problem with the same Chrome build (Version 64.0.3282.119 (Official Build) (64-bit)); on Windows 8.1 Pro x64 with SBIE 5.22; no problem before and no problem outside of the sandbox, of course. Tried in a clean sandbox with all data deleted, and installed Chrome outside the sandbox. This was especially annoying since I am simultaneously experiencing the Firefox no audio and video playback bugs, and so both my browsers are knocked out. Needless to say, very annoying, and nontrivial to downgrade Chrome particularly as it requires a full delete with many minutes to get everything set up again. Thanks.

Chrome is failing to work with Sandboxie since the latest update on my Win 10 x64 machine. However it IS working as normal with the same version of Chrome on my Win 7 x64 machine. Both received the latest Chrome updates this afternoon to 64.0.3282.119.

On my Win 10 machine I cannot load any webpage or even anything from the menu (like settings) without getting the same message on Chrome that another person wrote above :

"Aw, Snap!
Something went wrong while displaying this webpage."

If it helps I have identical software set ups on both machines (including Chrome extensions), and both are fully patched with all the latest Windows updates. The only difference is the actual OS (Win 7 vs Win 10). I am using avast free and MBAM Pro. OH hang on a tick!! Just remembered, there is a difference in sandboxie version! The working version on Win 7 is 5.23.3 and my Win 10 machine it's still 5.22. Is anyone on 5.23.3 and having this Chrome issue?

I updated to Chrome 64.0.3282.119 and also updated all "Components" (chrome://components/).

When using Sandboxie's template to force Chrome to run sandboxed it works OK here, with Sandboxie 5.23.3 on 64-bit Windows 10.
I have seen a couple of times a message flash on the screen - something about a network change.

I have only these extensions Enabled:
